A method I have used in the past.....take a 1/4" bolt .....put on a nut....run it up the bolt, now put a 1/4" spacer that about 1/2" long or some 1/4" washers (all available from a home diys center) thread the bolt in the bushing. While holding the bolt still, tighten the nut toward the bushing. It should tighten on the bushing without tighting the bushing any. then back the bolt out with bushing attached.
